Cannot adjust the brightness after display driver update on Satellite L855-118
I just bought a SATELLITE L855-118, with ATI graphics card today, it was between this and another of them, but I know that you have problems updating graphics drivers on a portable Sony.
I did a restore point.
So I uninstalled the ATI catalyst graphics card and then did a sweeper driver and rebooted and then installed catalyst 12.6, installed fine, but my screen went to the maximum brightness and I can't adjust, BRIGHTNESS osd is displayed but the brightness of the screen does not change.
So I used my restore point.
This time I crushed the catalyst 8.9 with 12.6 stock, still cannot adjust the brightness.
Someone knows how to solve this problem.
My spec full in the link below.
You mean that you can not use the Fn or Fn + F6, F7 button combination?
Do other combination works properly?
Also check this doc:
There is a brightness.zip that installs the additional registry key
Hello. I have a Dell XPS 15 L521X. Recently updated to Windows 10 and I can adjust is no longer my brightness upwards or downwards.
Now the screen is quite low. I'd say about 30-40% brightness. 10 widows I found about 5 different places to adjust your brightness and I made sure all of them have been set to 100%. I have my power plan to high performance and I went into advanced settings and turned off Adaptive brightness and made sure that the brightness of the screen the two Dim brightness set to 100% on battery & are plugged. Rebooted and still dim.
My question is, on Dell laptops, Windows has full access to the brightness control? Or Dell replaces Windows with their software customized for the display settings? When I bought this laptop in 2012, the software, at the time, was called Dell QuickSet. What is the responsible application of brightness of the screen control? And is it necessary?
I am also having this same problem. My brightness has been set at max after update and it hurts my eyes. I did it... Control Panel > Device Manager > graphics cards > Intel HD Graphics 4000 > pilot > Update Driver > Browse my computer > let me pick. Choose Microsoft Basic graphics card.
After doing this, my problem was solved, and I was able to adjust the brightness of my screen again. BUT if you play games on your laptop, it will cause display problems in your game.
After update of windows 8 and installed the latest AMD driver on the Toshiba site, I cannot adjust the brightness of the screen using the Fn F2 or F3.

I m using the Pavilion 15-r004ne on a windows 64-bit OS 8.1 and I cannot adjust the brightness of my screen. I tried to adjust by shortcut keys F2 and F3, tried adjusting via the mobility Center, tried through Control Panel and so on, but no response until now. It shows the little pop-up when I press the keys. But nothing has changed, the brightness of the display remains the same. in order to get solution soon.
Thank you for your support. It didn't work either. I solved the problem of roll back the driver and update again.
I have recentlly installed win 7 rc on my G530 and I cannot adjust the brightness and more. I have download the hotkey driver features that now allows me to adjust the volume and everything but the screen brightness... y at - it a specific driver, I need to download for this? Thank you.
Nevermind I solved this isue. I have download Lenovo Hotkey features and executed the file as administrator with Vista compatibility mode:
problem solved. I also updated the bios.
After you have installed Windows 8.1, I can't adjust the brightness of the screen more. I checked and updated all the drivers and nothing helped. There used to be a brightness slider in the control panel in the power settings. It's over now. I've looked everywhere for a solution, but I can't seem to find it. Any help would be greatly appreciated.
Here are the specs of my computer:
HP Pavilion 23-F213W Smart Touch
Many All in One computers are able to use HP MyDisplay in this http://www.portrait.com/dtune/hpc/enu/index.htmlplace. There is a list of maps videos supported on this page and should help to restore the video controls setting.
I have a Pavilion dv2945se notebook. I have completely updated the Nvidia geforce 7150 m drivers. My laptop came with Windows Vista Home Premium 64-bit, and I did a new install of Windows 7 Home Premium 64-bit. I can't adjust the brightness of the display. I narrowed down the problem to the generic PnP Monitor driver. How can I solve this problem?
Edit: I mean "impossible to adjust the brightness of the display" that every time I go into power options and trying to use the cursor, Windows Explorer crashes. Also, my fn + F7 and F8 keys light work before I connect to windows, but not after. I think that something will charge when I connect to windows that is causing the problem. So I went in Mode safe, but then all that allows to control the brightness has not loaded when I went into safe mode, which was not helpful. I also went into MSConfig and disabled all startup programs, but again, I have the same problem. The brightness of the keys work before connect you to Windows, but not thereafter.
When I turn off the device generic PnP monitor (1) can't adjust the brightness at all and (2) the Power Options window stops freezing. That's how I've narrowed the problem to the generic PnP Monitor driver.
I finally solved this by uninstalling the driver for the ALPS touchpad. Because there are no Windows 7 drivers for my laptop even though it is listed in the models capable of upgrading to Windows 7, I used Windows Vista touchpad drivers. It was the cause of my problem with brightness adjustment. I don't know why it worked, but I've narrowed it down by disabling all processes start and then from their one at a time to see what caused the problem. As soon as I started Apoint.exe, I started to have problems.
Now, I just have to find a way to disable the touchpad tapping without the ALPS drivers.
So I tried different ways to resolve this issue, but again the light cannot be turned on/off. Help, please!
There are two Intel driver links to the choices on your laptop support page.
I explored the folder of the driver of this driver file to support your laptop and driver page, and it is suitable to use driver.
This package provides the driver that allows graphics Intel high definition (HD) in the notebook models that are running an operating system supported. If the video output high-definition multimedia interface (HDMI) is supported, this package also installs the HDMI Audio Driver.
File name: sp69589.exe
The hardware ID for the Intel graphics card in your laptop must be one of these...
; Windows 8.1 install
% iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_220F103C
% iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_2213103C
% iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_2210103C
% iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_2214103C
You should see a device from Intel HD graphics instead of the graphics card base of Microsoft, and unless you can get the graphics driver to install you will not be able to adjust the brightness of the screen.
Is the above driver do not install the Intel graphics card automatically, try to install the driver manually by navigating to the folder of the driver that is created after running the above file.
Confirm that the hardware for the Intel graphics card ID matches one of the above since the driver installation information file that I posted.
To find the ID of the hardware, Device Manager, click the graphics card Microsoft Basic.
Then click on the Details tab in the upper part of the window Microsoft Basic graphics card.
Now you should see a drop-down list of property and it is set by default to the Description of the unit.
On this list and select the 3rd point (Hardware ID).
Confirm that the hardware ID, you see there is one of those listed that I posted.
Hello my f11 and f12 keys is no longer adjust my brightness. The gauge up and down, but does not change the brightness. I tried to update the graphics card in Device Manager, but he says that it is up-to-date. Same thing with 'Generic PNP Monitor' said that it is up-to-date. I wiped the computer clean and 'reset' and reinstalled windows and it still does not allow me to adjust the brightness of the screen
I'm not incredibly intuitive with computers, but I followed the instructions as much as I could find during my research online with nothing doesn't.
Initially, the problem occurred when I used out of ignorance a program to install the drivers it says have been exceeded. After that, my audio stop working and my keyboard stop working entirely. After resetting the computer and windows resettled, the only question that remains is the brightness of the screen not being able to be adjusted.
This drives me crazy, can anyone help me? I would be very happy! and please let me know if you need more information regarding my laptop. Thank you!!
I thought about it. My drivers intel had to be installed since I reinstalled windows. I used the utility of intel and updated driver to update the graphics card update
I have been using my yoga 2 with an external monitor via micro-hdmi port, but a week ago, it stopped working. The monitor does not recognize laptop. In addition, I can't adjust the brightness of my laptop screen, the keyboard, or in the control panel in windows. I think that this problem started after a windows update, but I'm not entirely sure. Does anyone know a fix? Thank you!
Welcome to Lenovo forums
For external monitor, please try another cable and another screen if available or check if the cable and the screen work fine with other devices
For brightness problem please try to go to under view Device Manager right click on the Intel driver cards and choose Properties
On the driver tab, click roll back driver, if it is dimmed, try to download and install the driver from the link below
Please let me know what happens
Hello everyone. I just bought a new L540 with 8.1 of Windows x 64 on it and have met a problem that I see is apparently common. While my other Fn keys work as expected, I can't adjust the brightness of the screen with them. By pressing the buttons just does nothing and the laptop is in running at full brightness at any time, even on the battery. I installed the latest driver for managing power and from what I can tell, there is no version of the management software supply for something newer than Windows 7. I also installed the latest driver for the shortcut key (in fact, I installed all the latest drivers for this machine.) I read in another thread that this may be caused by the latest driver from Intel's HD graphics card but in fact, I can not install even this driver (said my system is not supported) so I always use the latest version of the driver Lenovo provided.
Can someone please help with this? I want to be able to quickly adjust the brightness of the screen when it is on battery, but I can't do it right now. Thank you!
I have the same problem with my L540. It started with the BIOS update to version 1.65. Because I have not found a solution, I went back to BIOS version 1.64, where all the brightness options are there and are working properly.
You can download older versions. When on the page with the new drivers (http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS037285) go to BIOS driver 1.65, then choose "learn more." At the end of the next page, you will see all the old versions.
You can install the version 1.64, you should choose the Option "Secure RollBack prévention" in the BIOS: restart the computer. When you see the option "to interrupt normal startup, press enter", press ENTER. Once more, press ENTER. Press F1 to enter BIOS Setup utility. Click on 'Security'-> then "update Bios UEFI Option'-> then"set RollBack prevention. " Change this option to "disabled". Press F10 to save the configuration changes and exit.
After you restart Windows, you can install BIOS 1.64.
Another possibility is to wait for the next version of BIOS...
After a new installation of Windows 7 64 bit Home Premium on my HP Pavilion dv6, I find that I can't adjust the brightness/contrast of the screen. Initially, I had installed a generic pnp Monitor driver, but after reading a solution which recommends to uninstall, I did, but to no avail. I have also tried installing HP Support Assistant, scanned my laptop computer for outdated drivers and have installed the recommended drivers, but I am always faced with the same problem.
If you provide me with any details on my laptop, let me know.
I realized later that I had 215 updates of windows install. After I did, the problem solved itself, but I think that among the updates has been one for the graphics driver.
Thanks for your response!
I have a laptop HP ProBook 4445 s, and this afternoon I noticed that my screen is small, so I tried to adjust the brightness, but it doesn't work. Last week, I update my OS Windows 8.1. I do not download drivers from other sites.
What should do?
Try to use Recovery Manager to reinstall your original graphics driver (Intel, Nvidia, AMD etc.) - the procedure to use the Recovery Manager to reinstall the drivers and software is detailed in the document in question on the link below.

I'm not sure when this problem started, but I'm guessing it's when I've updated my graphics driver (Nvidia) or software of the chipset (Intel).
After a while, I noticed that my brightness keyboard shortcuts were not working, but other hotkeys (touchpad, volume, sleep, wi - fi, bluetooth, etc.) were still working.
Since I use my laptop for most on my desk with the max brightness settings, I ignored it for a while.
When I happened to use up the outside of the battery, the monitor went automatically minimum brightness settings.
I tried to find the brightness slider in the control panel or the mobility Center, but they have been missing.
The options for the Adaptive brightness disappeared as well.
Now I don't see a way to adjust the brightness of my.
I tried a variety of suggestions available on the web, including:
create a new user account,
validation of account information,
Remove and reinstall the driver for the monitor,
search for 'brilliance' in the start menu,
re-installation of software hotkey,
rolling back the graphics drivers and chipset (from those provided by the manufacturer).
I spoke with a Microsoft support for topic a couple of hours, still no luck (he was very nice anyway).
If anyone is suggesting the control panel Windows or Nvidia color grading, I don't mean for those, since I need to adjust the brightness of the backlight of the screen, not software-ish of calibration of the colours on the screen.
I use Windows 7 Ultimate on CLEVO M860TU with monitor Chi Mei N154Z1-L02
I am looking for a way to restore the brightness sliders, or at least to adjust the brightness manually.
When I had to happen, I was able to restore by doing this:
(1) open Device Manager
(2) right click and uninstall the monitor (not the graphics driver, but the monitor specifically)
3) click on the "Scan for new hardware" button on the toolbar above
(4) try to use the brightness slider functions once again (either in Center of energy or mobility settings).
Has worked for me, I would like to know if it helps you too.
I can't adjust the brightness of my screen...
